Solution Overview

Problem

Traditional mobile phone cases do not effectively distribute shock, leading to potential damage from impacts, as they primarily provide an additional layer without adequate shock absorption and dispersion capabilities.

Innovation Solution

The mobile phone cover incorporates protrusions on its inner and outer surfaces, including thicker corners and arrays of oval or X-shaped protrusions, which reduce contact surface area and dissipate impact energy through flexible materials and air pockets, providing shock absorption and dispersion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional phone cases provide an additional layer, then aesthetic and storage features are improved, but shock absorption and dispersion capabilities are insufficient

Engineering Contradiction:
Improveprotection capabilityVSAvoidshock impact
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The back wall is segmented into multiple protrusions instead of a flat surface. Each protrusion acts as an independent shock-absorbing element, dividing the impact force across multiple contact points rather than concentrating it on a single surface.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protrusions create localized contact points with the phone back, concentrating shock absorption at specific locations while maintaining overall coverage. The varying heights and shapes of protrusions provide different levels of cushioning in different regions.

Inventive Principle:
Principle #3Local quality

2Strength

If protrusions are added to reduce contact surface, then shock absorption is improved, but device complexity increases

Engineering Contradiction:
Improveshock absorptionVSAvoidcover structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

Multiple protrusions are integrated into a single molded cover structure, combining what would otherwise be separate components into one unified piece. This reduces assembly complexity while maintaining the shock-absorbing functionality of multiple contact points.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The protrusions serve multiple functions simultaneously: they provide shock absorption, create air pockets for additional cushioning, and maintain aesthetic appearance. This multi-functionality reduces the need for additional separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The cover effectively absorbs and disperses impact energy, reducing the transfer of shock to the phone, enhancing protection against drops and maintaining functionality.

Implementation Method 1

one or more protrusions disposed on an inside portion of the back wall, wherein the one or more protrusions reduce the contact surface between the cover and the mobile phone and provide shock absorbing characteristics

Methodology Applied
Scientific EffectShock absorption: Damping

Implementation Method 2

These protrusions can provide the shock absorbing characteristics at least along a length, a width, and/or a diagonal axis of the cover

Methodology Applied
Scientific EffectElasticity: Elasticity

Implementation Method 3

The phone case can also have at least one row of protruding features arranged inside the base envelope along an inner-facing side wall and configured to protrude to the same extent as each other from the side wall to touch the side of a smart phone and maintain resilient contact therewith while creating air pockets therebetween

Methodology Applied
Scientific EffectCompression: Compression

AI summary

Disclosed are covers for a mobile phone including aspects that protect the phone from impact and/or provide shock absorbance characteristics. Covers can include one or more protrusions that reduce the contact surface to the phone and dissipate energy. Advantageously, the one or more protrusions work with intermittent spaces to provide shock absorbing characteristics and reduce the contact surface area between the cover and the phone. In some embodiments, the protrusions can include a soft-side rectangular shape, where the protrusions are placed in an ordered array in the back wall of a cover. In some embodiments, the one or more protrusions can include a row of x-shaped protrusions interspersed with air pockets along the inside wall of the cover.
